libexif ------- DESCRIPTION ----------- libexif is a library for parsing, editing, and saving EXIF data. It is intended to replace lots of redundant implementations in command-line utilities and programs with GUIs. FEATURES -------- libexif supports parsing, editing and saving of EXIF data. In addition, it has gettext support. All EXIF tags described in EXIF standard 2.1 are supported. REQUIREMENTS ------------ libexif is written in plain C and does not require any additional library. LIMITATIONS ----------- libexif can only handle some maker notes, and even those not very well. More work needs to be done. Note that libmnote has been merged with libexif - it is no longer needed. FRONTENDS --------- Right now, I know of the following frontends to libexif: - exif: A small command-line utility to show EXIF information in JPEG files (http://www.sourceforge.net/projects/libexif). - gexif: A GTK+ frontend for editing EXIF data (http://www.sourceforge.net/projects/libexif). - gphoto2: A command-line frontend to libgphoto2, a library to access a wide range of digital cameras (http://www.gphoto.org). - gtkam: A GTK+ frontend to libgphoto2 (http://www.topfrose.de). - thirdeye: Digital photos organizer and driver for eComStation (http://ecomstation.ru/thirdeye). - digicam: If you would like to migrate your program to use libexif or add EXIF support to it, don't hesitate to contact the authors. LIBRARIES --------- I know of the following libraries that use or have been inspired by libexif: - pel: PHP-Code (http://pel.sourceforge.net) TODO ---- We should probably support the generation of an empty EXIF structure with all mandatory tags. First ideas are in exif-tag.c. This has not yet been finished. AUTHORS ------- libexif has originally been written by Curtis Galloway . Because of the original design not supporting editing and saving, Lutz Müller rewrote libexif from scratch.
